sgcl VS kit

The SGCL repository contains the source code for this benchmark that uses the tracked pointers: https://github.com/pebal/sgcl/blob/main/examples/treap/treap...

You can look at the SGCL garbage collector for C++: https://github.com/pebal/sgcl. It works in a separate thread, is locks-free and never stops the world.

It will never be called gc_ptr because C++ programmers have an allergy to the term GC. However, an attempt was made to implement a similar solution. Take a look at tracked_ptr: https://github.com/pebal/sgcl

SGCL is a real-time garbage collector for C++ without any pauses.

Removed GC support was useless. You can have GC pointers in C++.

Mutators are threads that allocate memory and manipulate pointers, they can work completely independently of the GC. A mutator needs only to tag an object when copies or moves a pointer to this object. The GC detects this tag and marks the object as alive. Here is a working implementation for C++: https://github.com/pebal/sgcl

I don't know Rust but you can have a pauseless GC in C++. You just need to provide asynchronous access to root pointers.

In a toy language, with such a destructive move, I tried making use of it: https://github.com/srh/kit/blob/master/phase5/box.ki (Note that it has a default implementation of the move operation defined by the "move" keyword -- nowhere in the project is there a need for a manual implementation via a "do_move" implementation.) It worked fine for recursive data structures, because the language had tagged unions and no inheritence.
